This is very useful for generating configuration file examples. * the section that this key belongs to. Again very useful for generating configuration file examples. ## Using Environment Variables If you wish to allow environment variables to be used as the value of configuration keys, just call the `allow_environment_variables` method in your `config.py` file: ```python from derpconf.config import Config Config.allow_environment_variables() ``` If there's an environment variable with the same name as the given configuration, derpconf will give precedence to it, instead of using the default value or the value in the configuration file. ```python # called program with SOMETHING=value myprogram.py assert config.SOMETHING == "value" # even if the default for 'SOMETHING' or the value in the config file is different from 'value' ``` ## Reloading Configurations After you've loaded configurations from a file, sometimes it's needed to have them reloaded. This is the case when a new module needs to define some new default values. In order to reload values from a config object, just call `reload` on it: ```python from derpconf.config import Config conf = Config.load('/path/to/my/cfg.conf') # then later on... Config.define('SOMENEWFOO', 'bar', 'baz', 'foo') conf.reload() assert conf.SOMENEWFOO == 'bar' ``` ## Generating Configuration Examples To generate a configuration example, you just need to call the `get_config_text` method. Let's see an example: ```python from derpconf.config import Config Config.define('foo', 'fooval', 'Foo is always a foo', 'FooValues') Config.define('bar', 'barval', 'Bar is not always a bar', 'BarValues') Config.define('baz', 'bazval', 'Baz is never a bar', 'BarValues') config_sample = Config.get_config_text() print config_sample # or instead of both, just call generate_config() ``` The following text will be print into the standard output: ```python ################################## FooValues ################################### ## Foo is always a foo ## Defaults to: fooval #foo = 'fooval' ################################################################################ ################################## BarValues ################################### ## Bar is not always a bar ## Defaults to: barval #bar = 'barval' ## Baz is never a bar ## Defaults to: bazval #baz = 'bazval' ################################################################################ ``` A good sample of using derpconf can be seen at [thumbor's configuration file](https://github.com/globocom/thumbor/blob/master/thumbor/config.py). ## Verifying a Configuration File derpconf includes a configuration file verifier. The purpose of this verifier is to help you quickly understand what configuration files are missing what keys and what values will be used for them instead. Running it is as simple as including a call to `verify_config` in your `config.py` file: ```python verify_config(file_path) ``` Or you can leave it blank and derpconf will get the file path from `sys.argv`: ```python verify_config() ``` The output of the verifier is something like this: ```python Configuration "baz" not found in file /Users/bernardo/dev/derpconf/vows/fixtures/missing.conf. Using "bazval" instead. Configuration "foo" not found in file /Users/bernardo/dev/derpconf/vows/fixtures/missing.conf. Using "fooval" instead. Configuration "bar" not found in file /Users/bernardo/dev/derpconf/vows/fixtures/missing.conf. Using "barval" instead. ``` You can see it in use at [derpconf's code](https://github.com/globocom/derpconf/blob/master/derpconf/config.py). ## License derpconf is licensed under the MIT License: The MIT License Copyright (c) 2012 globo.com timehome@corp.globo.com Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
